Matrix metalloproteinase gene polymorphisms and susceptibility to systemic sclerosis
(2016) [Artigo de periódico]The major pathological hallmark of the systemic sclerosis (SSc) is skin and internal organ fibrosis, which results from normal tissue architecture alterations and extracellular matrix (ECM) protein deposition. ECM components ... -
Matrix metalloproteinase gene polymorphisms in patients with coronary artery disease
(2007) [Artigo de periódico]Matrix metalloproteinases (MMPs) play an important role in the pathogenesis of atherosclerosis, the pathology underlying the majority of coronary artery disease (CAD). In this study we tested the hypothesis that polymorphic ... -
Matrix stiffness mechanically conditions EMT and migratory behavior of oral squamous cell carcinoma
(2019) [Artigo de periódico]Tumors are composed of heterogeneous phenotypes, each having different sensitivities to the microenvironment. One microenvironment characteristic – matrix stiffness – helps to regulate malignant transformation and invasion ... -
Maturation of pyramidal cells in anterior piriform cortex may be sufficient to explain the end of early olfactory learning in rats
(2020) [Artigo de periódico]Studies have shown that neonate rodents exhibit high ability to learn a preference for novel odors associated with thermotactile stimuli that mimics maternal care. Artificial odors paired with vigorous strokes in rat pups ... -
May polyester with collagen coating mesh decrease the rate of intraperitoneal adhesions in incisional hernia repair?
(2013) [Artigo de periódico]Background - Among meshes used in incisional hernias in open technique repair, the polypropylene is the most commonly used due to flexibility, cellular growth stimulation, satisfactory inflammatory response, easy manipulation ... -
MBL2 gene polymorphisms and its relation to infection in Brazilian systemic lupus erythematosus patients : a 10-years followup study
(2022) [Artigo de periódico]Introduction: Systemic lupus erythematosus (SLE) is a multifactorial disease and MBL2 genetic variants, which are associated to differential peripheral MBL levels, potentially affect its etiology and increase infection ... -
MBSP1: a biosurfactant protein derived from a metagenomic library with activity in oil degradation
(2020) [Artigo de periódico]Microorganisms represent the most abundant biomass on the planet; however, because of several cultivation technique limitations, most of this genetic patrimony has been inaccessible. Due to the advent of metagenomic ... -
Measurement of sulfatides in the amniotic fluid supernatant : a useful tool in the prenatal diagnosis of metachromatic leukodystrophy
(2022) [Artigo de periódico]Metachromatic leukodystrophy (MLD) is an autosomal recessive lysosomal disorder caused by deficiency of arylsulfatase A (ARSA), leading to an accumulation of sulfatides. Sulfatides have been quantified in urine, dried blood ... -
Meat market reaction towards mass media and science communication on bovine spongiform encephalopathy
(2013) [Artigo de periódico]This study assesses the correlation between reports on food risk published in scientific journals and in the printed mass media and changes in the meat market. It focuses on the case of bovine spongiform encephalopathy ... -
Mecanismos moleculares no hirsutismo : expressão gênica de enzimas do metabolismo androgênico no folículo piloso e associação com o diagnóstico etiológico
(2003) [Artigo de periódico]Androgens are the main hormonal regulators of human hair growth and they are related to clinical conditions such as hirsutism. The aim of this study was to analyze the gene expression of androgen receptor (AR), type 1 and ... -
Mechanisms underlying the antiproliferative effects of a series of quinoxaline-derived chalcones
(2017) [Artigo de periódico]The present study aimed to characterize the effects of quinoxaline-derived chalcones, designed on the basis of the selective PI3Kγ inhibitor AS605240, in oral cancer cells. Three lead compounds, namely N9, N17 and N23, ... -

Melanoma hereditário : prevalência de fatores de risco em um grupo de pacientes no Sul do Brasil
(2004) [Artigo de periódico]FUNDAMENTOS - Aproximadamente 10% dos casos de melanoma são atribuíveis a mutações em genes de predisposição, sendo, portanto, hereditários. OBJETIVOS - Este estudo avalia a prevalência de fatores de risco para melanoma ... -
Melatonin analgesia is associated with improvement of the descending endogenous pain-modulating system in fibromyalgia : a phase II, randomized, double-dummy, controlled trial
(2014) [Artigo de periódico]Background: Central disinhibition is a mechanism involved in the physiopathology of fibromyalgia. Melatonin can improve sleep quality, pain and pain threshold. We hypothesized that treatment with melatonin alone or in ... -
Melatonin is a biomarker of circadian dysregulation and is correlated with major depression and fibromyalgia symptom severity
(2019) [Artigo de periódico]Objective: This study compared urinary 6-sulfatoxymelatonin (aMT6s) over 24 hours among fibromyalgia (FM), major depression disorder (MDD), and healthy control (HC) groups, and examined whether rhythm is correlated with ... -
